The present invention relates to improve 7 thereof which is herein exemplified, a locoments in the tanks of locomotive tenders.v

Heretofore, in locomotive practice, the fuel chambers of locomotive tender tanks have been fabricated or built up of metal plates riveted or welded together in their positions in the tank. Due to the acid formed by the afiects of the elements on the coal, such plates have been subjected to rapid deterioration from rust and other chemical reactions. The cost of cutting and fitting the plates and riveting and bolting thesame-has been substantial and replacement or repair of the plates has involved great expense.

The object of thisinvention is to provide a tender tank having a fuel chamber disposed therein, formed as an integral casting, which structure will avoid the aforesaid undesirable characteristics of the fabricated cha n: bers and materially reduce both the cost of manufacture and maintenance of the tender tank. Another object of the invention is to provide such a chamber having a fuel conveyor compartment also .formed integrally therewith. And, a further object is to provide such a chamber having a conveyor trough and conveyor shaft bearing also formed integrally with the fuel chamber. The invention is illustrated in the accome panying drawings, in which v 1 t Figure 1 is a partial side view of the locomotive tender showing the invention applied thereto; Fig. 2 is a front view of the same; Fig. 3 is an enlarged longitudinal section of the fuel chamber on the line III-III'of,Fig.

4; Fig. 4: at the right half is a front end view of Fig. 3, and at the left half is 'a section on the line IV-IV ofFig. 3; Fig. 5 is a half plan view ofv the same; Fig. 6 isa longitudinal section on the line VI-VI of F ig. 7, showing a modified form of the fuel,

chamber; and Fig. 7 at the right side is a front end view, and .at the left side i'safsem tion on the. line VIIVII, ofiFig. -6.-,

In the. practice of the invention, referring descriptively to, the specific; embodiment motive tender tank, indicated generally by the numeral 1, is supported on the longitudinal beams 2 of the tender frame and is connected thereto in the usual manner. The tank embodies the usual water section 3, formed by side plates 4,..whi'ch are turned at their front ends to form'front plates 5, bottom plates 6, and the usual rear and roof plates (not shown), allof which plates are suitablyv attached together'in the usual manner. 1 1

Thefuel chamber is formed as an integral one piece casting, indicated generally by the tal Walls 11 are disposed, a space being left between their inner edges for the passage of fuel therethrough to the rectangular convey- ,or' compartment formed by the walls 9, 10

and 11.

At the rear of the fuel chamber, an inclined wall 12 extends fromvthe top ofthe tender tank, inwardly downward to the rear end of the walls 11, the walls8, 11 and 12, forming a hoppercompartment for thefuel chamber.

'Spaced to the rear of the connection of walls lland 12, a vertical wall 13 extends downward from theisaid wall 12 to the rear end 7 ofthe bottom wall 10, closing the conveyor compartment, An opening 14 isprovided in the Wall 12 between its connections to the walls 111 and 13, andjan opening 15*is, pro vided at the rear end of the bottom Wall 10,

the openings 'aifordingaccess to the conveyor compartment and being provided with suitv able cover plates (not shown) Strengthen ing ribs are provided at suitable points of jointure of the walls as indicated at 16, 17 and 18, and the inclined walls 8 are reinforced by ribs 26. The inner edges of the horizontal walls 11 are formed with fianges19 adapted to engage cover members (not shown), in such places as may be desired.

In Figures 6 and 7, a modified form of the conveyor compartment is illustrated. The said compartment is closed by a wall 20 providing a completely enclosed chamber to the rear ofthe same and walls 21 are extended downwardly and inwardly from the inner edges of the walls 11 meeting at their lower ends at the center of. the tank and forming a conveyor trough beneath the open passageway 22. Bracing legs 23 are formed between the bottom wall 27 and the bottOm oftlie trough. The rear wall 20 closes the end of the trough and forms a walled chamber to the rear of the same. The said wall 20 is formed with a bearing 24 adapted to support the rear end of a conveyor shaft, longitudinally disposed in the trough and having a screw formed thereon, as indicated in the dotted lines (Fig. 6). Suitable gears 25 are connected to the shaft for'operating the same, within the said chamber to the rear of the wall 20, said chamber providing a housing for such gearing. The bottom wall 27 of this structure is formed with openings 28 for the purpose of reducing the weight of the casting.

Vlhile there has, hereinbefore, been clescribed and illustrated, preferred forms of construction of the invention, it will be obvious that many and various changes in procedure, form, arrangement, and construction of parts may be resorted to and that this invention, therefore, is not limited to the particular embodiment disclosed but includes all and any such changes and modifications as come within the spirit and scope of the invention as described in the appended claims.
